You know the third pig won't open the door, not by the hair on his chinny-chin-chin, and you clearly can't huff and puff the house down, so you decide to go straight for the chimney.
You know that in the story the third pig put a pot of boiling water on the stove to kill the wolf, but hopefully you will have the element of suprise and the pig won't have time to light a fire. All the same, you keep a close eye on the fireplace as you wriggle yourself into the chimney.
Unfortunately it turns out the pig won't need to boil a pot. You've put on so much weight after eating the first two pigs that you get stuck fast in the narrow chimney! You're unable to budge neither up or down, and are wedged tight, with your head sticking out of the chimney pot and your footpaws dangling down over the hearth.
